ARTICULATED CAR.

Application filed October 23, 1925. Serial No. 64,290.

This invention relates to railway cars and has for an object the provision of means for locking the body and truck of a car together in such a manner that they may freely swivel relative to each other and at the same time are held together against vertical separation.

Another object of the invention is to provide means for locking the body center bearing members of the adjacent bodies of an articulated car to the center bearing member of a car truck to prevent said body center bearing members from accidentally becoming separated from said truck center bearing member and from each other.

Another object of the invention is to provide means for locking the body and truck of a car together by removable means which are secured together and engage the body and truck center bearing members, such means being arranged beneath the car floor and above the truck, thus obviating the removal of a portion of the car floor when it is desired to separate the body and the truck.

These and other objects will be apparent from the following description Referring to the drawings in which like reference characters refer to like parts, Fig.

lie a sectional plan view of portions of the adjacent ends of two adjacent cars mounted on a truck bolster and Fig. 2 is a vertical sectional View of the same taken on the longitudinal center line of the car.

Referring now in detail to the drawing the reference character 1 indicates an articulated car which comprises a plurality of bodiesl the adjacent ends of portions of two of such bodies being illustrated. The adjacent ends of these two bodies are supported by a truck 2 which may be of any suitable construction but which in the drawing preferably comprises a truck bolster 3 which is mounted in the truck frame 1 in the usual manner. Secured to the bolster there is a center bearing member 5 which has a bottom portion 6 on which a concave bearing sur face 7 in the form of a portion of a sphere is formed. Extending upwardly from the portion 6 there 1s an annular portion 8 which 15 vertically disposed. This portion is provided with spaced horizontally disposed lugs 9 which are preferably continuous throughout the circumference of the portion 8 and form a groove 10, the use of which will hereinafter be described.

Each of the end portions of the adjacent 5 ends of two adjacent bodies is provided with a downwardly depending portion 11 which extends into the truck center bearing member 5 and has a convex bearing surface 12 in the form of a portion of a sphere which is adapted to slidably engage the surface 7 of the truck center bearing member. In plan View the portion 11 is bevelled from the center line of the car toward each side thereof so that when the two adjacent ends of the two adjacent bodies are in their proper positions relative to each other and the surfaces 12 of such portions are in engagement with the surface 7 there willbe sufficient clearance between the ends of the bodies to permit them to move freely relative to each other in rounding curves.

The end portions of the two adjacent bod= ice are held in spaced relation through the medium of a spherical member 13 which is loosely mounted in recesses 14 formed in such end portions. This member besides maintaming the bodies in spaced relation, also prevents the underframe of one body from rising above the underframe of the adjacent body, thus preventing the telescoping of the bodies in a collision. This construction is more fully set forth in No. 1,608,795, dated Oct. 19, 1926 U. S. Patent, in the name of Alfred Pehrson, for connection for, articulated cars.

Above the portion 8 of the truclr center bearing member, the portions 11 of two adjacent car bodies are provided with outward 1y extending curved lugs 15, there being sufiicientclearance between thelower surfaces of these lugs and the portion 8 of the truck center bearing member to permit free swivel ing movement between the portions 11 and the truck center bearing member.

For the purpose of counteracting any tendency of the adjacent ends of adjacent bodies to separate vertically from the truck accidentally, and to assist the portion 8 in resisting any tendency of the bodies to separate longitudinally, a ring member ld is provided. This member preferably comprises two semicircular parts which are preferably of channel form in cross section having a vertically disposed web 17 and horizontally disposed inwardly extending top and bottom flanges 18 and 19 respectively. Each of these parts, at each end is preferably pro= 'jacent bodies.

vided with an outwardly extending flange 20. hen these parts are in their proper locking positions the adjacent flanges 20 are secured together through the medium ot a bolt 21, there being a filler 22 interposed be tween the flanges which can be removed and replaced by fillers ot difi'erent thicknesses, thus providing for adjustments in the S1256 of the ring.

lVhen the ring is in its proper position on the car and the parts thereof are secured together, the bottom flange 19 is seated in the groove 10 in the truck center bearing member and is thus held against vertical movement relative to the truck center bearing member 5, while the top flange 18 overlies the lugs 15 on the portions 11 of the ad It will here be noted that there are spaces 23 between the under surface of the flange 18 and the upper surfaces of the lugs 15 and between the under surfaces of the lugs 15 and the upper surface of the portion 8 ot the truck center bearing member, thus permitting a tree swi elin movement'ot the bodies relative to each other and to the truck. It will further be noted that should the portions 11 have a tendency to rise vertically relative to the truck center bearing member the upper surfaces of the lugs 15 will engage the under surface of the flange 18 ot the ring, thus counteracting such tendency.

In the foregoing description the truck center bearing member 5 has been described as being secured to a bolster movably mounted in the truck frame, but it will be understood that this center bearing member may be made integral with the bolster and in some cases may be mounted on or integral with a component part of the truck frame in such cases as there is no bolster.

Having thus described the invention what Iclaim as new and desire to secure by Let-- ters Patent is:

1'. In an articulated car comprising a plurality of bodies, a truck supporting the adjacent ends of said bodies and av ring memher for locking together said truck and bodies against accidental vertical movement.

2. In an articulated car comprising a plurality of bodies, a truck supporting the adjacent ends of two of said bodies, and a member channel shaped in cross section adapted to cooperate with said truck and said bodies to counteract any tendency to excessive vercenter bearings for preventing excessive vertical movement between the body and truck center bearings.

41-. In an articulated car comprising a plurality of bodies, a truck for supporting the adjacent ends of two of said bodies, a center bearing between said truck and said bodies, and a ring member cooperating with said bearing to counteract excessive vertical moven'ient between said truck and said bodies.

5. A connection for the adjacent ends of two bodies of an articulated car, comprising body and truck center bearing members, a member loosely mounted in said ends above said bearing members, and means engaging said center bearing members adapted to counteract excessive vertical movement between said bearings.

6. A connection for the adjacent ends of two bodies of an articulated car, comprising a member loosely mounted in said ends adapted to prevent vertical movement of one of said bodies relative to the other of said bodies, body and truck center bearing members, and means engaging said center bearing members adapted to prevent excessive vertical movement therebetween.

In an articulated car comprising a plurality of car bodies, a truck supporting and connecting the adjacent ends of two of said bodies, means for preventing relative vertical movement between said bodies, and means independent of the first mentioned means for preventing excessive vertical movement between said bodies and truck.

' 8. In an articulated car comprising a. plurality of car bodies, a truck for supporting the adjacent ends of two of said bodies, a truck center bearing on said truck, body center hearings on said bodies adapted to cooperate with said truck center bearing, and means adapted to engage said body and truck center bearings for maintaining said bearings in their proper cooperating positions.
